Enjoy the warm weather because this is nothing. It is going to get much colder. MUCH colder. The sun is in minima. I have heard that it might last 70 years. Some say up to 200 years. No one knows how long the minimum will last.
I posted up the downwelling UV chart for SSDD a day or so back showing the drop out of radiation in the DW-UV spectrum. The portion of the spectrum that is capable of warming oceans is cooling and the energy is moving to longer wavelengths. Its will cause O3 depletion above the poles allowing more rapid cooling along with reduced energy into our oceans.
Cooling is already evident and its only been about 20 years since the sun began this reduced energy output state. while TSI (Total Solar Ir-radiance) has remained fairly constant and only dropped 0.3% the internal shift of energy to longer wavelengths is having very marked reactions on earth.
